MEANS FOR CONTROLLING THE FLOW OF GASES.

SPECIFICATION forming part of Letters Patent No. 752,299, dated February 16, 1904.

Application filed May 2, 1903.

To all whom it may concern} Be it known that I, PIERRE PLANTINGA, a

' citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Means for Controlling the Flow of Gases, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to means for controlling the flow of gases, and is particularly applicable for use in the purifying apparatus of illuminating-gas plants. As so particularly applied such means are commonly called center valves.

The object of the invention is to produce means whereby the gas may be caused to flow in either of two directions through each of two purifying-compartments, through both in the same or through one in the direct and through the other in the reverse direction, or may be caused to by-pass both compartments simultaneously.

Said invention consists of means hereinafter fully described, and particularly set forth in the claims.

The annexed drawings and the following descriptionset forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a vertical axial section of a center valve with supply, discharge, and auxiliary pipes attached and shown broken and partly in section. Fig. 11 represents aplan view of the valve with the upper and lower caps removed,

showing a portion of the two connected puri-- fying-compartments in horizontal section.

Figs. Ill and IV represent a horizontal section and a plan view, respectively, of the upper cap. Figs. V and VI represent a horizontal section and a plan view, respectively, of the lower cap for a cap, showing the position of said Fig. V11

given direction of flow of the gas.

represents a group of views similar to those Serial No. 155,240. (No model.)

shown in Figs. III, IV, V, and VI, showing the relative positions of such two caps for a second direction of flow of said gas; and Figs. VIII to XIV, inclusive, illustrate such relative position-for other different directions of flow.

The two purifiers A and B are substantially identical in construction, contain the purifying medium, and are each provided with a gasinlet a and b and a gas-outlet a. and I), through which gas may enter and depart. Inlet-pipes a and b and outlet-pipes a and 6 are connected with the inlets and outlets or, a, I), and b, respectively, as shown in'Fig. II. These pipes c 6 00 and I)", all have their other ends secured to a distributing-section C of the center valve, which .is formed with a central upright duct 0, open top and bottom,

and five by means of radial partitions, as shown in Fig. 11. These chambers are all open at the top and closed at the bottom, as shown. Chambers C and C each have a lateral opening, to which are connected elbows, to which are connected, respectively, the pipes b and a Chambers C and C similarly connect with pipes 01, and 6 To the bottom of the duct 0 is secured an elbow, to which is secured a gas supply pipe D. Chamber C is laterally connected with a gasdischarge pipe D. It will therefore be seen that there are formed six gas-ducts by means of these pipes, elbows, and chambers, the extremities of which are placed in juxtaposition and terminate in the plane of the top of the distributin -section C. The outer wall of such section is made cylindrical, and its upper periphery is formed with a flange a, forming a bearing for a cap E, which I shall designate as the lower cap. This cap is cylindrical in form, of a diameter substantially equal to that of the distributing-section C, and divided into five chambers E, E E E and E by means of radial partitions, as shown, around central duct e, which is coaxial with the duct 0. Chamber E is covered and opens into the duct 6, which is also covered, the remaining chambers being open top and bottom. The upper periphery of cap E is formed with a flange e, which forms a bearing for cap F',.which I shall designate as the l upper cap. This cap covered, and the bottom thereof lies substane tially flush with the bottom of partitions f and f. formed a bearing f which'engagesa centering-pilot 6 formed upon the top of and coaxial with cap E. The partitions in cap E do they also with the top thereof. therefore be seen that by rotating the two caps E and F various combinations of connections may be formed, the chambers C C &c., E

placed as illustrated in the group of figures,

E, &c., and G and 'Hforming when superposed segregated duct-sections, as will be understood from the foregoing description.

I shall now describe various positions of the upper caps for effecting varying paths of flow' of the gas. The relative positions of said caps being as illustrated in Figs. III, IV,

V, and VI, it will be noted that chambers. E, i

rectly to the exclusion of compartment A, the

EZE E*, and E and chambers C, 020 ,0 and C respectively, are superimposed, and chamber H of cap F, connects chambers E and E The gas passing from the source of supply through pipe D flows into duct 0, thence into duct a, chamber E (chamber E and hence pipe 72 being cut ofi',) chamber C through pipe (0 into the purifying-compartment A,through opening a into pipe of, into chamber E, chamber H, across and into chamber E chamber 0 and thence into pipe D, from whence it is discharged. The gas thus passes directly through but one purifying-compartment, A, and is cut off from communication with the other compartment, B.

When it is desired to reverse the above-described direction, the caps are placed as illustrated in the group of figures marked VII. In this case the gas enters,as before, through pipe D into duct 0, duct 6, chamber E and then chamber C, pipe (0 compartment A, through opening a, pipe (4 into chamber 0 chamber E*, chamber H, chamber E, chamber C and thence into pipe .D, thus reversing the direction of flowthrough the compartment A.

To pass the gas through both chambers simultaneously and directlythat is, into openings a and b and out of openings a. and b the two caps are placed relatively to each other, as shown in the group of figures marked VIII. The gas now passes from chamber E into C through pipe (1. through compartment A, out of opening a, .through pipe 01, into chamber C, up into chamber E, into chamber H, across and into chamber E, down into chamber 0*, through pipe 6 into and through compartment B, out through opening 6, through pipe 6 into chamber C up. into chamber E f, intochamber G, across andinto Chamber E down into chambenCi, and so out through pipe D.

A-t'the junction of the latter is To pass the gas directly through compartmentA and in the reverse direction through compartment B, the caps are placed as illustrated in the group of figures numbered IX. In this. case the gas passes reversely through the compartment A, as previously described,

- but upon returningto the distributing-section E passes up through chambers C E into chamber H, across into chamber E chamber C, thence'into pipe 12 and so directly through also lie flush with the bottom of the cap, as..,

It will.

compartment B, out of opening 1) into pipe 6 up through chambers C E into chamber G, and so across to chambers E 0 and so out through'pi-pe D.

To by-pass both compartments, cap E is numbered X, by means of-which latter it will be seen that thegas passes directly from ducts 0 and 6 into chambers E and C and so out, all

: other. ducts being closed to its passage. The 5 position of the cap F is in this case obviously immaterial.

To pass the gas through compartment B dicaps are placed as illustrated in the group of figures numbered XI. The gas passes from ducts c and e into chambers E C, pipe 6 compartment B, pipe 6 chambers C 'E H E 0 and out through pipe D. To pass the gas through the compartment B in the reverse directionto the exclusion of compartment A, the caps are placed as illustrated in the group of figures numbered XII. In this case the gas passes through ducts c and e, chambers E C pipe Z2 compartment B, pipe 6 chambers C E H E and thence out.

To pass the gas through chambers B and A directly, the caps are placed as shown in the group of figures numbered XIII. In this case the gas passes through ducts 0 and e, chambersE (1*, pipe 6 compartment B, pipe 6 chambers C EH E C pipe a compartment A, pipe a chambers C E G E C and thence out.

To pass the gas through compartmentB in the reverse direction and then through oompartment A directly, the caps are placed as shown in the group of figures numbered XIV. In this case the gas passes through ducts c and e, chambers E G pipe Z2 compartment B,

pipe I), chambers C E H E C pipe a compartment A, pipe 0 chambers C E E C and thence out. w

It is obvious that the direction of the gas in the supply and discharge pipes D and D may be reversed-that is, the gas supply may be taken through pipe D and the gas discharged through pipe D in which event anyone of. the above-described paths of movementmay be obtained reversed.

Other modes of; applying ;the principle of my invention may 'beremployed instead ofthe oneexplained, change being made as regards the mechanism herein disclosed provided the means stated by any one of the following claims or the equivalent of such stated means be employed.
